API "/oauth/request_token" returns {"errors":[{"code":215,"message":"Bad Authentication data."}]}



Hi, guys
I have tried to connect from web-app to get token for my application account, but Twitter returns the error message like this:
{“errors”:[{“code”:215,“message”:“Bad Authentication data.”}]}
Anybody know something about this error?
PS My request:

How are you generating the request?


I used DHC for test. For generate Authorization was used PEGA application with common features (connectors to Twitter).


This is the connector’s Authorization settings


I don’t know what any of those acronyms mean but the signature method should be HMAC-SHA1. Do you have any code sample?


Thanks a LOT Abraham!!! It’s worked now)))
